Suitable driving means are provided for'the pulling up wheels.

A machine constructed according to this invention is illustrated in the accompanying drawings. Figure 1 of the drawings shows a section through the end of the air pipe with the hollow cartridge mounted thereon. Figure 2 is a front view of the flattened lower tapered end of the tenter frame. F igure 3 shows the finishing rolls, their operating mechanism and theraising and lowering gear for the tenter frame. Figures 4:, 5 and 6 show the automatic stop device associated with the tenter frame cable. Figure 7 is a fabric. Figure 8 is a corresponding view to Figure 3 but, in a plane at right angles thereto.

Figure 9 shows a side view partly broken away of an alternative form of the frame and Figure 10 shows a section on the line IX-IX of Figure 9.

The removable cartridge 1 carrying a length of the fabric to be. treated (not shown) is mounted on a fiange2 at the upturned end of the air pipe 3, the latter being carried by supports on the ground floor A of the factory. The cartridge 1 has the fish ,tail end piece 4 fitted over its upper end.

The tenter frame may either project below the level of the top of the fish tail when in its operative position, as shown in Figures 1 and 2, or may terminate above this level.

i For some cases thelatter position is preferable.

* The tenter frame, whose total length is 7 preferably from 6 to 20 feet, consists of two lateral members comprising curved strips 5 carrying antifriction rollers 6, the latter being preferably of aluminium or aluminium alloy, and two cross members joining the lateral members and comprising rods 7 carried in hollow shafts 8 The rods 7 are attached to dummy rollers 6 mounted in the strips 5 similarly to the guide; rollers 6. The length of the cross members can be adjusted by sliding the rods 7 in or out" of the shafts 8, removable pins 9 cooperating with holes 10 in rods 7 to hold the rods in their adjusted position. The shafts 8 are centrally carried in holes bored in solid sections of a central verticaljshaft 11 and are brazed thereto. The shaft 11 which is hollow over most of its length can be attached at its upper end to a cable 12 by means of which the tenter frame canbe raised and lowered; When the tenter frame is lowered into its operative position the lower end of the shaft '11 passes into and is supported by a hollow sleeve 13 which is rigidly mounted on the floor A and projects axially through the upturned end of the air.

pipe. The sleeve 13 is bell-mouthed to facilitate location of the shaft 11. The tenter frame is entirely supported by rod 11 which is maintained vertical in the socket 13 and is prevented from swinging by the outsiderollers 16 which are operated by theright andleft screw on shaft 17 to approach and recede from rod 11 equally. By

terminating socket 13 below the 7 base of cartridge 1, it is apparent that when the rod ,7 upper floor .13 of the factory, as shown in view in the plane of Figure 3 of the tube for inducing convection currents round the the stationary vertical tube 14 is provided with glass panes 15. Alternatively the tube or frame 14 could' be made of transparent material.

It sometimes happens, especially when a big stretch is required on the tenter frame,

that the fabric sags. To' counteract this, grooved pulling up wheels 16 (Figure 8) are provided, one at each side of the tenter frame, which may be brought into contact To enable the operator on the floor with the outside of the fabric by turning the left and right hand threaded shaft 17 by means of the hand Wheel 18. When the wheels 16 are in contact with the fabric the antifriction rollers 6project into the groove of the wheels 16. The wheels 16 are preferably covered with a material such as rubber or felt in order to obtain a good grip on the fabric.

are driven from the main pulleyshaft 20 through the variable cone gear 21, the chain gear 22 and the bevel gear 23. More than one pair of Wheels 16 may be provided. Rubber coated wheels in contact with the Springs 19 act on the wheels 16 to impart an even pressure. The wheels 16' outside of a tubular fabric on a stretcher for assisting the passage of the fabric over the stretcher are not in themselves new.

The tenter frame can be raised when the.
